Boron (chemical symbol B)
แปลว่า(english) Element N. 5 of the periodic system. Atomic weight 10.82. It is gray in color, ignites at about 1112 (degrees) F. and burns with a brilliant green flame, but its melting point in a non-oxidizing atmosphere is about 4000 (degrees) F. Boron is used in steel in minute quantities for one purpose only- to increase the hardenability as in case hardening and to increase strength and hardness penetration.
Zircon
แปลว่า(english) The mineral zircon silicate, ZrSiO4, a very high melting point acid refractory material used as a molding material in steel foundries.
Braze Welding
แปลว่า(english) A family of welding procedures where metals are joined by filler metal that has a melting temperature below the solidus of the parent metal, but above 840 (450 C).
Zinc
แปลว่า(english) Chemical Symbol Zn. Element No. 30 of the periodic system; atomic weight 65.38. Blue-white metal; when pure, malleable and ductile even at ordinary temperatures; melting point 787 (degrees) F.; boiling point 1665 (degrees) F., specific gravity 7.14. Can be electrodeposited; it is extensively used as a coating for steel and sheet zinc finds many outlets, such as dry batteries, etc. Zinc-base alloys are of great importance in die casting. Its most important alloy is brass.
high melting poit grease
แปลว่าจารบีชนิดที่มีจุดแห่งการหลอมละลายได้สูง หรือละลายมาก ใช้สำหรับอัดลูกปืนเครื่องปั๊มน้ำ
Burn
แปลว่า(english) 1) Process of cutting metal by a stream of fuel and oxygen, 2) to permanently damage a metal or alloy by heating to cause either incipient melting or intergranular oxidation.
Basic Oxygen Process 2
แปลว่า(english) A steel making process wherein oxygen of the highest purity is blown onto the surface of a bath of molten iron contained in a basic lined and ladle shaped vessel. The melting cycle duration is extremely short with quality comparable to Open Hearth Steel.
Burning
แปลว่า(english) (1) Permanently damaging a metal or alloy by heating to cause either incipient melting or intergranular oxidation. (2) In grinding getting the work hot enough to cause discoloration or to change the microstructure by tempering or hardening.
